2024年6月，中国在西昌卫星发射中心成功发射风云四号03星（FY-4C），这是我国新一代静止轨道气象卫星风云四号系列的第三颗业务星。该卫星由长征三号乙运载火箭送入预定轨道，标志着我国高精度、高频次、全天候气象观测能力迈上新台阶。风云四号03星搭载了先进的多通道扫描成像辐射计、干涉式大气垂直探测仪和空间环境监测仪器，可实现对地球同步轨道区域每5分钟一次的快速成像，并提供高时空分辨率的大气温湿廓线数据。这不仅显著提升了对台风、暴雨、强对流等极端天气的监测预警能力，也为气候变化研究、生态环境监测和防灾减灾提供了重要支撑。作为国家民用空间基础设施的重要组成部分，风云四号系列卫星已广泛服务于全球120多个国家和地区，其数据被世界气象组织纳入全球业务应用气象卫星序列。此次03星的成功发射，进一步增强了我国在全球气象观测体系中的影响力，彰显了中国在航天科技与气象服务领域的自主创新能力和国际责任担当。
In June 2024, China successfully launched the Fengyun-4C (FY-4C) meteorological satellite from the Xichang Satellite Launch Center. This marks the third operational satellite in China’s new-generation geostationary Fengyun-4 series. Launched aboard a Long March-3B rocket into its designated orbit, FY-4C significantly enhances China’s capability for high-precision, high-frequency, and all-weather meteorological observation.Equipped with an advanced multi-channel scanning radiometer, a geostationary interferometric infrared sounder, and space environment monitoring instruments, FY-4C can capture rapid full-disk images of Earth every five minutes and deliver high-resolution atmospheric temperature and humidity profiles. These capabilities greatly improve early warning and real-time monitoring of extreme weather events such as typhoons, heavy rainfall, and severe convective storms, while also supporting climate research, ecological monitoring, and disaster prevention efforts.As a key component of China’s civilian space infrastructure, the Fengyun-4 series serves over 120 countries and regions worldwide. Its data has been integrated into the World Meteorological Organization’s global operational satellite network. The successful launch of FY-4C further strengthens China’s role in the international meteorological observation system, highlighting its growing innovation capacity and global responsibility in aerospace technology and meteorological services.
